With sound money 1) you can’t know exactly how rich someone is who doesn’t want to share that information with you voluntarily, 2) you can’t force anyone, rich or poor, to involuntarily pay taxes they don’t want to pay.  So how does your system work then, if not he rich your system wants to tax says “no” other than centralizing the power to…oh, Idunno, say 51%, to force them?  

Tell me, then what do you have? 

 Edit: “…if the rich in your system…”

Sorry.
